Find all the second partial derivatives. v = e5xey

Mathematics

Helga [31]3 years ago

I'm taking the liberty of editing your  function  <span>v = e5xey:  It should be 
</span>
<span>v = e^5x^ey, with " ^ " indicating exponentiation.
</span>
Did you mean e^(5x) or (e^5)x?  I'll assume it's e^(5x).

The partial of   v = e^(5x)e^y with respect to x is e^(5x)(5)*e^y, or 25x*e^y.

The partial of v = e^(5x)e^y with respect to y is e^(5x)e^y.

kia thinks she can make her new product for $5.80. She plans to sell for $12. what is her percent mark up?
gavmur [86]
First, count the difference of the cost production and the selling cost
difference = 12 - 5.8
difference = 6.2

Second, transform the difference to percentage
percentage = difference/product cost × 100%
percentage = 6.2/5.8 × 100%
percentage = (620/5.8) %
percentage = 106.9%

The mark up cost is 106.9%

Find the HCF of 126 and 420
melamori03 [73]

Answer:

42

Step-by-step explanation:

Find the prime factorization of 126

126 = 2 × 3 × 3 × 7

Find the prime factorization of 420

420 = 2 × 2 × 3 × 5 × 7

To find the GCF, multiply all the prime factors common to both numbers:

Therefore, GCF = 2 × 3 × 7

GCF = 42

Solve the following equations.<br> √3 ⋅ 3^3x = 9
GREYUIT [131]

Answer:

The solution is x = 0.5

Step-by-step explanation:

We need to write everything as a power of 3.

We know that:

\sqrt{a} = a^{0.5}

So

\sqrt{3} = 3^{0.5}

And

9 = 3^{2}

This following property is also important:

\frac{a^{b}}{a^{c}} = a^{b-c}

To solve, the first step is putting everything with the variable x on one side and everything without the variable x on the other side

\sqrt{3}.3^{3x} = 9

3^{0.5}.3^{3x} = 3^{2}

3^{3x} = \frac{3^{2}}{3^{0.5}}

3^{3x} = 3^{2-0.5}

3^{3x} = 3^{1.5}

This means that:

3x = 1.5

x = \frac{1.5}{3}

x = 0.5
